What are the main advantages and disadvantages of object-oriented programming?

Object-oriented programming (OOP) has a number of advantages and disadvantages.

Advantages:

• Encapsulation: hiding the internal implementation of an object, which simplifies maintenance and data protection.
• Inheritance: allows creating new classes based on existing ones, reusing code.
• Polymorphism: objects of different classes can use the same interface, which facilitates extensibility.
• Modularity: code is divided into logical blocks (classes), improving readability and maintainability.

Disadvantages:

• Complexity: for simple tasks, OOP can be excessive and complicate the structure.
• Performance: due to additional abstractions, execution speed can sometimes decrease.
• Overcomplication: improper use of inheritance and polymorphism can lead to tangled code.

In iOS development, OOP is widely used, for example, in Swift and Objective-C, which helps structure code and manage complex applications.
